Choose Heise for your calibration needs

Heise instruments can be calibrated in an ISO 17025-accredited calibration laboratory, certified by the ANSIASQ National Accreditation Board(ANAB). We're available to certify pressure instruments with ranges from 0.25 inH2O up to 12,000 psi with accuracies as high has 0.025% of span.
We have a dedicated lab staffed with technicians who are trained and certified to perform ISO 17025 calibration certifications for any analog pressure gauge, transducer, handheld calibrator base unit, or pressure module that we make.

New PTE-2 Handheld Calibrator

Put an Even Better Pressure Test Lab in Your Hands...

The Heise® PTE-2 handheld calibrator offers, a USB port, SD card, backlit LCD and an onboard loop power supply. Like the original, the PTE-2 accommodates two Quick-Select™ modules to measure pressure in ranges from 0.25 in. of H2O through 10,000 psi and temperature over a wide range with RTDs or thermocouples. Equipped with input jacks for current and voltage, up to three measurements can be displayed simultaneously. In addition, a variety of menu-driven calibration and recording features is provided through simple front panel commands.

Now is the time to upgrade from PTE-1 to PTE-2 handheld calibrators by taking advantage of our special offer. Because the sensor modules are different sizes, we’ll provide up to four FREE new housing retrofits with the purchase of every PTE-2. With these simple housing conversions, you can continue to use your existing sensor modules. For details, please email: mike.cody@ashcroft.com
